Pregnancies after intrafallopian transfer of embryos.

Six patients with a history of infertility of more than 4 years were offered in vitro fertilization (IVF) followed by translaparoscopic embryo transfer to the fallopian tubes. Three of the patients became pregnant. In one patient the oocytes did not fertilize in vitro. Intrafallopian transfer of embryos may be an alternative to gamete intrafallopian transfer (GIFT) or IVF, especially in those cases where confirmation of fertilization is wanted.
